CRISPR-1 and CRISPR-2 spacer distribution in X. albilineans strain GPE PC73. Each box represents a CRISPR spacer, with the spacer positions numbered inside each
box from the trailer end spacer to the leader end spacer. Pink boxes = CRISPR-1 spacers.
Green boxes = CRISPR-2 spacers. Spacers showing nucleic acid identity with sequences
of strain GPE PC73 of X. albilineans are listed in three separated tables according to the origin of these sequences (a
same prophage region located between XALc_0170 to XALc_0242, phage and plasmid sequences
and a housekeeping gene, respectively). Some spacers are 100% identical to corresponding
sequences of strain GPE PC73 of X. albilineans. Percentage value is indicated in brackets only for spacers for which the percentage
identity is less than 100%.
